Dataset of Full-Scale Structural Strain, Vibration, and Acoustic Measurements from a Passenger Rail Vehicle Operating Under Service Conditions

Description

This repository contains a full-scale experimental dataset of structural strain, vibration, and acoustic responses collected from an executive-class passenger rail vehicle operating on a 1067 mm narrow-gauge railway network in Indonesia. The measurements were acquired under representative operating conditions including maximum speed (100 km/h), acceleration, deceleration, inclined curve, declined curve, and sharp curve manoeuvres. The dataset was obtained using synchronized multi-sensor instrumentation comprising: Ten three-element rosette strain gauges installed on the carbody, coupler assembly, and bogie structure. One triaxial accelerometer and two uniaxial accelerometers mounted at representative vehicle locations. Five Class-1 free-field microphones positioned inside the passenger cabin. The repository includes raw and processed measurement data covering three physical domains: Structural strain measurements recorded from rosette strain gauges. Vibration measurements in longitudinal, lateral, and vertical directions, including frequency-domain representations. Acoustic measurements including sound pressure level (SPL) data and one-third octave band spectra. Supporting materials are also provided, including sensor layouts, instrumentation schematics, metadata files, channel descriptions, acquisition parameters, and illustrative figures describing the experimental configuration. This dataset is intended to support numerical model development, calibration, verification, and validation activities in railway engineering. Potential applications include finite element modelling, structural dynamics, vibration analysis, fatigue assessment, noise and vibration (NVH) studies, vibro-acoustic simulations, digital twin development, machine learning applications, and comparative benchmarking investigations. The dataset provides a synchronized multi-domain experimental reference acquired under real operating conditions and may be reused for research and educational purposes.

Steps to reproduce

1. Instrument an executive-class passenger rail vehicle using the measurement configuration described in the accompanying manuscript. 2. Install ten FRAB-6-11 three-element rosette strain gauges at predefined locations on the carbody, coupler assembly, and bogie structure. 3. Install one Dytran 3413A1 triaxial accelerometer and two PCB 353B33 uniaxial accelerometers at representative vehicle floor locations. 4. Install five GRAS 46AE microphones at representative passenger-exposure locations inside the cabin. 5. Acquire synchronized measurements using the corresponding data acquisition systems: - DEICY DR-600 dynamic strain recorder - IMC ARGUSfit acquisition system - HEAD acoustics SQuadriga III system 6. Conduct measurements under six operating conditions: - Maximum speed - Acceleration - Deceleration - Curved incline - Curved decline - Sharp curve 7. Record strain, vibration, and acoustic signals simultaneously. 8. Process vibration data using Butterworth filtering and FFT analysis. Process acoustic data using FFT and one-third octave band analysis. Organize the resulting files according to measurement domain and operating condition.
